Halloween
is an annual celebration
held on **October 31st**, and it’s one of the oldest holidays in the world, with origins tracing back to the ancient **Celtic festival of Samhain**. The Celts believed that this day marked the end of the harvest and the beginning of winter, a time when the boundary between the worlds of the living and the dead blurred, allowing spirits to return to earth.

Today, Halloween is celebrated in various ways, including:

1. **Wearing costumes**: Both children and adults dress up in spooky or fun costumes inspired by ghosts, monsters, fictional characters, and more.

2. **Pumpkin carving**: Known as **Jack-o’-lanterns**, pumpkins are carved with scary faces and lit with candles inside.

3. **Trick-or-treating**: Children go door to door saying “trick or treat” to receive candies and sweets.

4. **Scary movies and stories**: Halloween is associated with watching horror films and reading stories about ghosts, spirits, and other creepy creatures.

5. **Parties**: Halloween-themed parties are held where people enjoy music, games, and spooky decorations.

Over time, Halloween has evolved into a global celebration of both fun and fright, especially popular in countries like the United States and Canada.
